Just changed my stock air filter with the screamin eagle stage 1 air filter. And discovered grit on the clean side. Is this bad and what should I do? Just hit 6200km. View attachment 5706

I got rid of the OEM filter cos my mechanic has had a couple of HD filters break up & get sucked into the motor,
K&N is working fine, I didn't want to take the chance.
